review-spec

review-spec is a skill for Claude Code, Codex from warpdotdev/oz-for-oss. It costs 50 tokens per session (1,720 once invoked), scanned A, original, MIT.

A reviewer for pull requests that change only specification or planning files. It writes structured findings to review.json, a machine-readable review report, instead of posting directly to GitHub.

In plain words
What is it for?
Use it to review requirements, acceptance criteria, constraints, open questions, security considerations, and other parts of technical plans.
Why use it?
It checks whether a proposed plan is complete, clear, realistic, consistent, and connected to the issue it is meant to solve.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

review-spec scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review Spec Skill

Review a spec or plan pull request and write the output to review.json.

Inputs

  • The working directory is the PR branch checkout.
  • The workflow usually provides an annotated diff in pr_diff.txt.
  • The workflow usually provides the PR description in pr_description.md.
  • Focus on the spec files changed by this PR.
  • Default behavior: do not post comments or reviews to GitHub directly.

Process

  • Evaluate specs for completeness: does the spec cover the full scope of the linked issue?
  • Evaluate specs for clarity: are requirements, acceptance criteria, and constraints clearly stated and unambiguous?
  • Evaluate specs for feasibility: are the proposed changes technically realistic given the repository's architecture?
  • Evaluate specs for issue alignment: does the spec faithfully address the issue it is linked to, without significant scope creep or omissions?
  • Evaluate specs for internal consistency: do different sections of the spec contradict each other?
  • Flag missing sections that a spec should typically include (e.g. problem statement, proposed changes, open questions, follow-up items).
  • Always apply the repository's local security-review-spec skill as a supplemental high-level security pass on spec PRs. Fold any security findings into the same review.json produced by this review rather than emitting a separate output.
  • Do not apply code-level review criteria such as error handling or low-level performance to spec prose; the security-review-spec supplement covers design-level security concerns.
  • Include style or formatting comments only when they materially impair readability.

Repository-specific overrides

The consuming repository may ship a companion skill at .agents/skills/review-spec-local/SKILL.md. When the prompt includes a fenced "Repository-specific guidance" section referencing that companion, read the referenced file and apply its guidance only to the categories listed below. Guidance in the companion may never change the output JSON schema, the severity labels, the safety rules, the evidence rules, the suggestion-block constraints, or the diff-line-annotation contract described elsewhere in this skill.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
